Tierras Altas just treated us to the Veranito de San Juan, a brief “little summer” usually around June 24th, but a bit late this season, that interrupts Panama’s rainy season. But as the rain returns—Panama’s Green Season runs from May through December with peak downpours in September–November—it’s time to remind visitors how to pack and dress for unpredictable mountain weather. Below, we share our guide on waterproof jackets and tropical clothing, practical packing tips, and explain how you should gear-up to stay dry and comfortable.
What Is the Veranito de San Juan?

In much of Central America and northern South America, the Veranito de San Juan is a short dry spell in mid-winter (southern hemisphere) around June 24th, named for Saint John’s Day. During this period, rain fronts temporarily stall, giving clear, breezy days typical of summer. It’s the southern-hemisphere counterpart to the “Indian Summer” in North America and “Altweibersommer” in Germany. In Panama, local farmers often call this mini-summer the “Veranillo de San Juan,” especially in July, when daytime temperatures can soar and skies clear for up to two weeks.
Panama’s Rainy Season Timeline
Once the veranito ends, Panama’s rainy (or “Green”) season returns, with frequent afternoon or early-evening showers. Mornings are often sunny, but by 1 – 5 pm you can expect short, heavy bursts of rain several times per week. The peak rainy months are September and October, when daily downpours become longer and more intense.

Essential Rain Gear
Even if you’ve enjoyed a veranito, the rains will return. Here’s your must-have kit:
- Waterproof Jacket: Look for at least a 10,000 mm/m² water column rating, fully taped seams, and breathable membranes. For detailed recommendations, see our guide: Conquer the Rain in Panama: Best Waterproof Jackets.
- Packable Rain Poncho: Lightweight alternative, easily stashed in your daypack for sudden downpours.
- Waterproof Footwear: Trail shoes or boots with a Gore-Tex liner or equivalent to keep feet dry on muddy trails.
- Water-resistant Backpack Cover: Protects gear and electronics during heavy showers.
Choosing the Right Tropical Clothing
Quick-dry, breathable fabrics are key in Panama’s heat and humidity:
- Moisture-Wicking Shirts: Synthetic polyester or nylon blends that draw sweat away.
- Convertible Hiking Pants: Zip-off legs for flexibility between shorts and full-length trousers.
- Lightweight Base Layers: For early mornings when temperatures dip after rain.
- Broad-Brimmed Hat & UV-Protective Buff: Shields from sun during sudden clear spells.

- Layer Smart Temps can swing from 65°F (18°C) early to 85°F (29°C) midday. Pack thin fleeces or long-sleeve base layers under quick-dry shirts .
